Subject: [PATCH 4/4] spi: s3c64xx: add support for exynos5440 spi
Date: Tue, 5 Feb 2013 15:09:44 -0800 [thread overview]
Message-ID: <1360105784-12282-5-git-send-email-ks.giri@samsung.com> (raw)
In-Reply-To: <1360105784-12282-1-git-send-email-ks.giri@samsung.com>
This patch adds support for the exynos5440 spi controller.
The integration of the spi IP in exynos5440 is different from
other SoC's. The I/O pins are no more configured via gpio, they
have dedicated pins.
